摘要: Direct numerical simulation of liquid-gas-solid flows is uncommon due to the considerable computational cost. As grid spacing determined by smallest involved length scale, large sizes become necessary -- in particular if bubble-particle aspect ratio on order 10 or larger. Hence, it arises question both feasibility and reasonability. In this paper, we present a fully parallel, scalable method for direct interaction at size 1-2 orders magnitude that makes simulations feasible currently available super-computing resources. With presented approach, bubbles suspension columns consisting more than $100\,000$ resolved particles possible. Furthermore, demonstrate significance particle-resolved comparison previous unresolved solutions. The results indicate fully-resolved indeed predict flow structure problems correctly.
